Linda is buying wool to knit a baby’s blanket.
Marrrta [24]

Linda needs to buy about 7 balls of wool to knit a baby’s blanket.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

1 yard = 36 inches

1 inch = 2.54 cm = 0.0254 m

Hence:

1800 yard = 1800 yard * 36 in per yard = 64800 in

64800 in = 64800 in * 0.0254 m per in = 1645.92 m

Since there are 245 metres of wool in each ball of wool. hence:

Number of wool balls = 1645.92 m / 245 m = 6.72

Linda needs to buy about 7 balls of wool to knit a baby’s blanket.

Maru [420]

y - y1 = m(x + x1)

m = (y2 - y1)/(x2 - x1) = (-6 - 2)/(-1 - 5) = -8/(-6) = 4/3

y - 2 = 4/3(x - 5) is a possible answer

y + 6 = 4/3(x + 1) is also a possible answer
